Abstract
Description
Technical Field
[0001] The utility model relates to air processing equipment, in particular to an air processing unit. Background Art
[0002] Air conditioning units (AHUs) are typically central air conditioning terminal units that use chilled / hot water as cooling and heating sources. They integrate a surface cooler, fan, and water pan into a single heat exchanger, delivering cooling or heating air. Based on panel structure, they are categorized as single-wall or double-wall AHUs, and as horizontal or vertical units. They are widely used in air conditioning systems for residential buildings, including electronics, pharmaceuticals, petrochemicals, laboratories, hospitals, hotels, and museums. Conventional AHUs primarily consist of a housing, internal filters, a heat exchanger, and a fan, focusing on temperature control. Their filters are typically composed of multiple pieces of filter cotton, which can only remove larger particles of dust and other impurities, resulting in limited dust removal effectiveness. As users' demand for higher air quality continues to rise, current AHUs are no longer able to meet these demands. Therefore, there is an urgent need to develop an AHU that can effectively improve air quality to meet customer needs. Utility Model Content
[0003] The purpose of the present invention is to provide an air handling unit that can effectively improve air quality.
[0004] The technical solution of the present utility model is as follows: an air handling unit comprises a box body, an air inlet is provided at one end of the box body, and an air outlet is provided at the other end of the box body; an inlet static pressure chamber, a filter dust removal chamber, a heat exchange chamber, a humidification chamber and an outlet static pressure chamber are sequentially arranged in the box body; a heat exchanger is provided in the heat exchange chamber, a humidification device is provided in the humidification chamber, and a fan corresponding to the air outlet is provided in the outlet static pressure chamber; a first filter screen, a plasma dust removal module, an electrostatic dust removal module and a second filter screen are provided in the filter dust removal chamber, which are vertically arranged side by side; the first filter screen and the second filter screen are both arc-shaped structures, and the concave surfaces of the first filter screen and the second filter screen correspond to the air inlet direction; a nano water ion sterilization module is also provided in the outlet static pressure chamber.
[0005] In the aforementioned air handling unit, a dehumidification chamber is provided between the filtering and dust removal chamber and the inlet static pressure chamber, and a dehumidifier is provided in the dehumidification chamber.
[0006] In the aforementioned air handling unit, the air inlet is connected to the return air outlet and the fresh air outlet through pipelines.
[0007] Compared with the prior art, the present invention completes the filtration and dust removal, heat exchange and humidification of the air by sequentially arranging an inlet static pressure chamber, a filter dust removal chamber, a heat exchange chamber, a humidification chamber and an outlet static pressure chamber in the box body, thereby ensuring that; at the same time, a first filter screen, a plasma dust removal module, an electrostatic dust removal module and a second filter screen are arranged in the filter dust removal chamber, and a nano water ion sterilization module is arranged in the outlet static pressure chamber. Through the mutual cooperation between the filter cotton, plasma dust removal, electrostatic dust removal and nano water ion sterilization technologies, the air quality is effectively improved. Moreover, the present application arranges the first filter screen and the second filter screen into an arc-shaped surface structure, and the concave surface faces the air inlet side, which can expand the contact area of the filter screen and improve the filtering effect. In addition, the present application arranges a dehumidification chamber on the air inlet side of the filter dust removal chamber for dehumidifying the air, which can not only remove some dust in advance, but also prevent the dust on the subsequent filter screen from sticking together under the action of moisture, thereby ensuring the dust removal effect.

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0011] Example. An air handling unit, comprising: Figure 1 As shown, it includes a box body 1, an air inlet 2 is provided at one end of the box body 1, and an air outlet 3 is provided at the other end of the box body 1; an inlet static pressure chamber 4, a filter dust removal chamber 5, a heat exchange chamber 6, a humidification chamber 7 and an outlet static pressure chamber 8 are sequentially arranged in the box body 1; a heat exchanger 9 is provided in the heat exchange chamber 6, a humidification device 10 is provided in the humidification chamber 7, and a fan 11 corresponding to the air outlet 3 is provided in the outlet static pressure chamber 8; a first filter 501, a plasma dust removal module 502, an electrostatic dust removal module 503 and a second filter 504 are vertically arranged side by side in the filter dust removal chamber 5; the first filter 501 and the second filter 504 are both arc-shaped structures, and the concave surfaces of the first filter 501 and the second filter 504 correspond to the air inlet direction; a nano water ion sterilization module 12 is also provided in the outlet static pressure chamber 8.
[0012] A dehumidification chamber 13 is provided between the filtering and dust removal chamber 5 and the inlet static pressure chamber 4 , and a dehumidifier 14 is provided in the dehumidification chamber 13 .
[0013] The air inlet 2 is connected to the return air outlet 201 and the fresh air outlet 202 through pipelines.
[0014] Preferably, the first filter screen and the second filter screen both include an upper filter screen and a lower filter screen that cooperate with each other, and the upper filter screen and the lower filter screen are rotatably connected to the filter dust removal chamber.
[0015] The inner top surface and the inner bottom surface of the filtering dust removal chamber are both provided with a accommodating groove corresponding to the shape of the upper filter screen and the lower filter screen, a rotating shaft is provided on one side of the accommodating groove, and a pulling slide is provided on the rotating shaft; the sides of the upper filter screen and the lower filter screen are both provided with a pulling slider that cooperates with the pulling slide.
[0016] The cross sections of the pull-out chute and the pull-out slider are both T-shaped structures.
[0017] The above structure, with the first and second filters arranged as a two-part, rotatable structure, allows the upper and lower filters to be hidden within the trough when not in use. When in use, they rotate 90 degrees, forming either the first or second filter, thereby meeting the requirements for handling varying air volumes. Furthermore, the upper and lower filters are pluggably connected to the rotating shaft, making replacement of the upper and lower filters easy. The curved structure of the filters also facilitates dust collection.
[0018] Preferably, an air monitoring sensor group is provided at the air inlet and the air outlet, the air monitoring sensor group is connected to a controller, and the controller is connected to a display screen located outside the box; the controller is also connected to a remote control center; and it also includes a heat exchange parameter monitoring sensor group that cooperates with the heat exchanger, and the heat exchange parameter monitoring sensor group is connected to the controller.

[0021] The air monitoring sensor group includes temperature sensors, humidity sensors, air volume sensors, wind speed sensors and air quality sensors.
[0022] The usage process of the utility model: when in use, the outside air enters the inlet static pressure chamber from the air inlet (the air equalization treatment is performed in the inlet static pressure chamber), and the air is monitored by the air monitoring sensor group. When the humidity is greater than the set value, the air enters the dehumidification chamber for dehumidification, and then enters the filter dust removal chamber for dust removal. When the humidity is less than the set value, the dehumidifier in the dehumidification chamber does not work; then, when cooling treatment is required, the air enters the heat exchange chamber, and the refrigerant circulates in the heat exchanger to cool the air; when heating is required, the heat medium flows in the heat exchanger to heat the air; then, the air enters the humidification chamber, and if humidification treatment is required, the humidification device performs humidification treatment, and then enters the outlet static pressure chamber, and after sterilization treatment by the nano water ion sterilization module, it is discharged from the air outlet under the action of the fan.
[0023] Humidity sensors are installed in the dehumidification chamber and the humidification chamber; a temperature sensor is installed in the heat exchange chamber.
[0024] Working process of the filtration and dust removal chamber: When the air enters the filtration and dust removal chamber, it is first filtered by the first filter, then filtered by the plasma dust removal module and the electrostatic dust removal module, and finally filtered by the second filter to complete the air filtration and dust removal operation.
[0025] When the air needs to be humidified, the humidifying device in the humidifying chamber will perform humidification so that the air humidity reaches the set value.
[0026] Furthermore, the cabinet's siding is made of double-layer colored copper or cold-rolled steel powder-coated (the inner side of the base is sometimes made of stainless steel), and the central insulation material is high-quality polyurethane foam. This polyurethane foam insulation material is more suitable for high-speed operation of the air handling unit and high cabinet vibration.
